Unlike real battles, the Battle Subway does not reward you with Experience Points or Money. Instead, you battle lines of trainers with select Pokemon to earn Battle Points (BP). The Battle Points can then be spent on items at the counter near each Subway. There are seven different types of battle subways, and one regular subway. From the door, walk counter clockwise to find each subway:

Rules

Select a Subway to battle at. Depending on the subway, you will choose 2, 3, or 4 Pokemon to use in seven battles. Two Pokemon are selected in Multi-Battles, three Pokemon are selected in Single Battles, and four Pokemon are selected in Double Battles. Some Pokemon are not allowed to complete, mainly Legendary Pokemon. Also, two of the same species will not be eligible, and no two Pokemon can have the same Hold Item.

All Pokemon in the Battle Subway will be at Level 50. If your Pokemon are above or below Level 50, they will be automatically adjusted to that level. Only Stats and Levels will increase. Your Pokemon's Moves will stay the same.

Regular Battles are easier than Super Battles. Most of the Pokemon in Regular Battles are unevolved or only once evolved. Almost all Pokemon are fully evolved in Super Battles. The more battles you win, the tougher the Pokemon become. Super Battles will unlock once you complete the regular battle train (21 consecutive battles) and obtaining the National Pokedex from defeating the Elite Four.

After selecting your Pokemon for battle, your team will fight in seven successive battles. Items cannot be used in battle, but Hold Items will be allowed. If your Pokemon uses a one-time use hold item in battle, it will be restored in the next battle. Pokemon are fully healed after each match. You are also given the option of continuing to the next match or quitting. When a Pokemon faints in Subway battles, the opponent's next Pokemon will be selected without allowing your team to switch to another Pokemon.

Earn Battle Points through seven successive wins. After seven, you are given a choice to continue or go back to Nimbasa City. If you continue, you can select a new team of Pokemon for the next seven battles.

Matches

Single

Single trains allow you to choose three Pokemon. All battles will be Single Battles.

He/She will ask if they should focus on offense, defense, or have a balanced team. Each player will choose two Pokemon, and all battles will be Double Battles.

After winning seven battles in a row, you are awarded with Battle Points. The Battle Points vary between Regular and Super Matches. After a set amount of battles in each Subway, you must fight the Subway Boss. In Regular Matches, you must win 21 matches. In Super Matches, you must win 49 matches.

Battle Point Store

The Battle Points you earn in the Battle Subway can be spent at the Battle Point Store. There is a desk with two clerks near each Subway. The left clerk sells Technical Machines, and the right clerk sells various other items.
